FirebaseMLException在Android上使用ML Kit识别图像中的文本

Question

我正在使用Google MLKit识别来自图片的文字。无法检测文本并进入onFailure回调，异常如下 com.google.firebase.ml.common.FirebaseMLException: batchAnnotateImages call failure

我正在使用云版本的Text识别API而不是设备版本。 代码如下

private void readFromCloud(Bitmap bitmap){
    FirebaseVisionCloudDetectorOptions options =
            new FirebaseVisionCloudDetectorOptions.Builder()
                    .setModelType(FirebaseVisionCloudDetectorOptions.LATEST_MODEL)
                    .setMaxResults(15)
                    .build();
    FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(bitmap);
    FirebaseVisionCloudTextDetector detector = FirebaseVision.getInstance()
            .getVisionCloudTextDetector();
    Task<FirebaseVisionCloudText> result = detector.detectInImage(image)
            .addOnSuccessListener(new OnSuccessListener<FirebaseVisionCloudText>() {
                @Override
                public void onSuccess(FirebaseVisionCloudText firebaseVisionCloudText) {
                    // Task completed successfully
                    // ...
                    readTextFromCloud(firebaseVisionCloudText);
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.e("FAILEd","Failed");
                    // Task failed with an exception
                    // ...
                }
            });
}

Stack Trace如下：
